It’s easier said that done. Because there’s a whole topic about copyright laws and the permissions to use the real world liveries.
In summary, airline companies reserve their full right to their own brand image and designs. And having anyone to simply create an accurate liveries of their brand image without their permission and consent is technically a breach of these copyright laws.
Now I know what you’re thinking. “But PC players have access to those said liveries and shared to flightsim.to or other sites, and they’re not in trouble”. Technically, in the eyes of the copyright laws, they are all breaching these laws. However, the enforcement of these laws to community-based addons are very gray and difficult to enforce and it all depends on how strict those brand image holders are about having their liveries re-created. So if an airline company decided to sue flightsim.to for sharing their liveries without their permission, or even directly to the livery author who made them in the first place, they’re within their rights to do so, and they’ll win the case.
However, suing someone, particularly an individual person or a freeware community is a costly endeavour for them, and they won’t have anything to gain in return. They won’t be able to sue someone for 10 million dollars in copyright infringement if the person doesn’t have that much money to begin with. So the worst scenario that’s usually happen is that the airline will send a notice of infrigement to the share sites, or the person directly asking them to remove the livery from the public space as it is within their rights as the true copyright holders, and they will have no choice but to comply, otherwise, they would be escalated to court and end up losing the money that you don’t have.
The best case scenario is that it doesn’t even get to their radar because they can see that these are merely community hobbyists and they have more pressing concern.
But when it comes to Xbox, because of the closed environment and everything has to go through the validity and the approval process to be loaded to the marketplace. Microsoft has full control over what goes through and what doesn’t. And this is the difference between PC community-based addons. Since Microsoft has full control over the contents, they’re more susceptible to copyright laws and its infringements. If the Airline sees their livery in the marketplace and they were not consulted or agreed on, they can sue Microsoft directly for allowing contents that infringe their copyright to the public without their permission. And they will do so because you can sue a company for millions of dollars for these.
The only way for airline liveries to be available in the Xbox marketplace is if either Microsoft/Asobo or any livery designer go to each airline legal department and specifically request the approval to create and publish their liveries into MSFS marketplace, and they will always have certain terms and agreements on what we can and can’t do with the liveries. If any of these terms and conditions are not agreed, they’re bust and we can’t have any of their liveries in the marketplace. Otherwise, if everything looks good, they would still monitor the livery designs themselves to make sure they’re following the brand policy and standards.
And these lengthy process has to be done for “each” airline. One at a time. I don’t know if this will ever happen, but I don’t envy the person who has to deal with these process just so we can have a livery that not everyone will use anyway.
